How does it compare to https://github.com/remirror/remirror?
bangle.dev aims to add little API overhead on top of Prosemirror (PM) whereas Remirror tries really hard to hide the PM API and attempts to provide its own React-ish abstraction. This might be a totally fine choice, but I went with the route of building reusable components instead of abstractions.
However, when I look at your docs, it's not clear it's a different in approach from Remirror. The imports are all from bangle.dev which makes it seem like the same approach.
I would love to see a doc explaining the "API overhead" and how to use PM directly. I want to feel confident I can easily drop back down to PM if Bangle doesn't have a feature I need or implements it in a way that won't work for our use case.
Really excited to see this approach! Shared PM plugins are a great idea!
Update: I created an abstraction called “feature” that seems to be similar to the extension concept, but different. Through features, editor creator can contribute related schema aspects and plugin views. Schema is always there and is not handled by a separate feature, however.
